Far off in the woods, there is a cabin. The cabin contains 3 people. 2 are in one room together, the other is by himself in another room. All doors to the cabin are locked tight and have not been opened. All three people are dead. There was no sign of violence in this cabin.
How did they die?

Can you figure out how this can be true? In a bedroom the nearest lamp is 12 feet away. Alone in the room and with our using any special devices such as cords,pulleys,remotes,or "the clapper," a person can turn off the lamp and make it to the bed before the room is dark. How?
